Questioning the value of mandatory code review is definitely the most popular underground belief held by senior engineers I know

Look at all these cowards faving this. Openly question the orthodoxy sheeple! I'm a manager my opinion doesn't matter anymore!

It's funny that every time I troll tweet about code review I can basically predict the responses:
Googlers defend it
A bunch of comments about it depends (yes obviously)
A few people 10+ years younger than me claim it could never be otherwise
Pair programming
